HTS heading 8455 is a broad product category for metal-rolling mills, the machinery that reduces or shapes metal by passing it between rotating rolls. It also covers the rolls used with those mills and certain parts designed for this equipment. The heading is a starting point, not usually the complete classification for an imported product.
To reach the correct 8-digit HTSUS code, first identify whether the item is a complete rolling mill, a roll, or a part. The subheadings then generally distinguish the equipment by its function or design and, for rolls or parts, by relevant characteristics such as material, construction, or intended use. Review the full legal description, including any notes and statistical subdivisions, rather than choosing from the heading title alone. Classification may require customs-broker or other professional judgment when the equipment is complex or could fit more than one provision.
What to check
- Identify the item’s role: complete rolling mill, replacement roll, or identifiable part made for a rolling mill.
- Document what metal the equipment processes, the rolling operation it performs, and whether it is designed for hot or cold rolling.
- For rolls, verify the roll’s material, construction, dimensions, and whether it is a work roll, backup roll, or another type described by the tariff.
- Use the complete HTSUS subheading text, Section and Chapter Notes, and applicable legal notes to narrow from heading 8455 to the 8-digit code.
- Compare the manufacturer’s specifications, drawings, invoice description, and prior rulings; ask a customs broker or seek a binding classification ruling if the facts are uncertain.

How to find your code in this category
A heading is a product category. To get the exact duty, narrow from this 4-digit heading to a sub-category (usually by material), then open the 8-digit code that matches your product.
Open any code in the tables below to see its exact duty rate, a duty calculator (enter your shipment value → estimated duty and landed cost), the rate-change history chart, and the country-by-country breakdown (including Section 301/232 add-on duties).
Why you have to click in: a single category can contain products with very different duties. The rate depends on the specific product — its material and construction — and on the country of origin, and those only get pinned down at the 8-digit code level. That is why this page points you to codes instead of showing one rate for the whole category.
